Question

graph the following data to determine the range of tolerance for catfish. the first number in each pair of data is temperature in degrees celsius; the second number is the number of catfish found in the stream: (0, 0); (5, 0); (10, 2); (15, 15); (20, 13); (25, 3); (30, 0); (35, 0). choose an appropriate scale and units for your graph. science notebook · principles of ecology 15

Explanation:

Step1: Identify x - and y - variables

The x - variable is temperature (in °C) and the y - variable is the number of catfish.

Step2: Choose a scale

For the x - axis (temperature), since the values range from 0 to 35, we can use a scale of 5 units per interval. For the y - axis (number of catfish), since the values range from 0 to 15, we can use a scale of 5 units per interval.

Step3: Plot the points

Plot the points (0, 0), (5, 0), (10, 2), (15, 15), (20, 13), (25, 3), (30, 0), (35, 0) on the graph.

Step4: Determine the range of tolerance

The range of tolerance is the range of temperatures where catfish are present. Catfish are present when the temperature is between approximately 10°C and 25°C.

Answer:

The range of tolerance for catfish is approximately 10°C - 25°C.
